Wind Engineering blog posts

Recent blog posts in this category include

• More on cross wind characteristics. A post setting out how calculated cross wind characteristics (CWCs) vary as the form of the lee rail rolling moment coefficient changes, together with an argument that current, complex methods for the calculation of CWCs are not appropriate. (Feb 26^th 2023)
• Measurements of carbon dioxide concentrations in a church. A post describing some measurements of Carbon Dioxide concentrations in St. Michael’s church in Lichfield on May 15^th 2022 (May 24th 2022)
• Pollutants, pathogens and public transport – ventilation, dispersion and dose. A post and downloadable technical paper describing a methodology for the systematic modelling of pollutant and pathogen concentrations during complete public transport journeys (16^th November 2021)
• The calculation of Covid-19 infection rates on GB trains. A post in which, using the work of Jimenez at Colorado, I present the results of some quantitative, if approximate, calculations of Covid-19 infection risk on trains in Britain. (June 16^th 2021).
• On April 19^th 2021 an online memorial event was held to celebrate the life of Prof Giovanni Solari of the University of Genoa who died five months previously. His career is well described in a memorial article in the Journal of Wind Engineering that can be found here. I was one of over 20 friends and colleagues who spoke at the event. This post is the  text of my short contribution (April 21^st 2021)
